12SB1800

12″SUBWOOFER
  • 4+4Ω nominal impedance
  • 3.6+3.6Ω minimum impedance
  • 2*1500 RMS capacity
  • 82 dB sensitivity
  • 39-1000 Hz response
  • 75mm(3in) inside-outside voice coil

12SB1800 is built for bass, with strong power carrying capacity and excellent control. The voice coil construction provides efficient heat dissipation and long-lasting thrust for stability at high outputs. Its low-frequency response is as deep as 40Hz, resulting in a wide and powerful soundstage. Whether it is used for car audio modification or other places, it can release shocking low–frequency energy.

This series began development in 2016 and was launched in 2017 after our engineers worked tirelessly to ensure top quality. Significant investment went into customizing the mold, as standard materials couldn’t meet our requirements. From design to material selection, every detail reflects the engineers’ dedication. With precise mechanical vibration damping, optimal q-value, and a special polymer material that balances lightness, stiffness, and damping, this speaker unit achieves high sensitivity and smooth, natural sound reproduction. Its high sound density, dynamic control, and clarity make it a remarkable speaker unit you won’t want to miss!
